Bonjour,
Je fais un petit ré-up de ma question ayant de nouveau éléments et donc de nouvelles interrogations.

Bon j'ai bien potassé les acl j'ai compris plein de choses et d'autres me reste encore obscure mais bon on avance :)

Alors voila j'ai refait mes ACL en respectant un ordre qui est censé permettre leur bon fonctionnement :

# ACL 1
# The userPassword by default can be changed
# by the entry owning it if they are authenticated.
# Others should not be able to see it, except the
# admin entry below
# These access lines apply to database #1 only

access to attrs=userPassword
       by dn="cn=admin,dc=immaculee,dc=net" write
       by dn="cn=adminro,dc=immaculee,dc=net" read
       by anonymous auth
       by self write
       by * none

# ACL 2
# régit les accès au paramètres de horde
access to attrs=hordePrefs,impPrefs,mailforward,vacationActive,vacationInfo
       by self write
       by * read

# ACL 3
# allow user to create entries in own addressbook; no-one else can access it

# needs write access to the entries ENTRY attribute (ACL4) and the
entries CHILDREN (ACL3)
access to dn.regex="ou=personal_addressbook,cn=([^,]+),ou=people,dc=immaculee,dc=net$"
  attrs=children
 by dn.regex,expand="cn=$1,ou=people,dc=immaculee,dc=net" write
 by users none

# ACL 4
# allow one to create entries in its own addressbook; no-one else can access it
# needs write access to the entries ENTRY attribute (ACL4) and the
entries CHILDREN (ACL3)

access to dn.regex="ou=personal_addressbook,cn=([^,]+),ou=people,dc=immaculee,dc=net$"
  attrs=entry
 by dn.regex,expand="cn=$1,ou=people,dc=immaculee,dc=net" write
 by users none

# ACL 5
# allow access to all entries in own addressbook; no-one else can access it

access to dn.regex="ou=personal_addressbook,cn=([^,]+),ou=people,dc=immaculee,dc=net$"
  filter=(objectclass=inetorgperson)
 by dn.regex,expand="cn=$1,ou=people,dc=immaculee,dc=net" write
 by users none

# ACL 6
# Ensure read access to the base for things like
# supportedSASLMechanisms.  Without this you may
# have problems with SASL not knowing what
# mechanisms are available and the like.
# Note that this is covered by the 'access to *'
# ACL below too but if you change that as people
# are wont to do you'll still need this if you
# want SASL (and possible other things) to work
# happily.
access to dn.base="" by * read


# ACL 7
# The admin dn has full write access, everyone else
# can read everything.
access to *
       by dn="cn=admin,dc=immaculee,dc=net" write
       by dn="cn=adminro,dc=immaculee,dc=net" read
       by * read

Zut j'envoi le message pas fini :(
bon bein suite et fin :)

Je pense qu'effectivement il me manque les droits sur la branche qui contient mon carnet, à savoir ou=personnal_addressbook mais bon je suis un peu perdu la franchement, je ne voudrais pas donner les droit write a tout le monde çà risque de poser problème.

Enfin si quelqu'un a une idée pour m'aider merci d'avance
